INFLUENCE OF IRRIGATION SCHEDULING, METHODS OF IRRIGATION AND NITROGEN LEVELS ON GROWTH AND YIELD OF MAIZE

Madras Agricultural Journal, 1994
Investigations were carried out in a split plot design replicated thrice with two levels of imrigation (0.50 IW/CPE ratio and 0.75 IW/CPE ratio), three methods of irrigation (all furrow method. alternate furrow method and paired skip furrow method) and three levels of nitrogen (75, 125 and 175 kg N ha-1.

[Irrigation management at the farm level]

1998
Des événements récents ont modifié, parfois bouleversé les systèmes irrigués dans le contexte français. Les conséquences économiques des dispositions de la réforme de la politique agricole commune concernant les grandes cultures ont conduit les agriculteurs à réviser leurs stratégies : économiser les intrants, limiter les charges de structure tout en ...

Cotton Response to Pre-plant Irrigation Level and Irrigation Capacity Using Spray, LEPA, and Subsurface Drip Irrigation

2003, Las Vegas, NV July 27-30, 2003, 2003
Wind incidence can affect microsprinkler water distribution. Evaluations in those conditions can be facilitated using simulations by computational models. The present work evaluates the performance of a ballistic model on simulating the wind effect on microsprinkler water distribution.

Irrigation management at the farm level

1997
L'objectif de ce document était d'élaborer une démarche pour aider l'agriculteur à raisonner l'organisation de sa campagne d'irrigation, pour l'ensemble de ses cultures irriguées, en cherchant à améliorer la cohérence entre ses objectifs de production, ses capacités d'irrigation (ressource, équipements, disponibilité en main-d'oeuvre) et ses modes de ...

Yield and Quality Characteristics of Drip‐Irrigated Soybean under Different Irrigation Levels

Agronomy Journal, 2018
Core Ideas Different irrigation levels affected the yield and quality components of soybean. Deficit irrigation decreased soybean protein content. Water deficit treatments caused an increase in the oil content in soybean. Soybean can be irrigated to 75% of Class A pan evaporation in semiarid conditions with limited water resources.

Automatic Control of Flows and Levels in an Irrigation Canal

IEEE Transactions on Industry Applications, 2009
Modernization of irrigation canals is becoming a strategic issue in many areas of the world with the purpose of improving the efficiency and the operational flexibility in water delivery. Apparently, small deviations in keeping flows at the desired scheduled values can lead to significant waste of water, which is particularly important in arid ...

Lateral Sizes for Efficient Level-Basin Irrigation

Transactions of the ASAE, 1981
ABSTRACT THIS paper describes a procedure by which a comput-erized data base of irrigated fields in a section of the Grand Valley was sorted to determine those fields with deep enough soils and mild enough slopes for practical basin leveling. Irrigation flow rate requirements for effi-cient watering of the resulting basins were determined.

Effect of Irrigation Level and Land Configuration on Beetroot

Journal of Experimental Agriculture International
In recent scenario of limiting water and land resources and beetroot is sensitive to water deficits broad bed and furrow planting technique is one of the new agronomic systems since its water saving and better nutrient utilization property which results in higher root yield.
